- Dinosaur (Wikipedia)
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is a subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya and their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds.
- Populism (Wikipedia)
Populism is a range of political stances that emphasize the idea of “the people” and often juxtapose this group with “the elite”. It is frequently associated with anti-establishment and anti-political sentiment. The term developed in the late 19th century and has been applied to various politicians, parties and movements since that time, often as a pejorative. Within political science and other social sciences, several different definitions of populism have been employed, with some scholars proposing that the term be rejected altogether.
